y ANDREW CHBIIS'TIANSON, OF BUTLER, PENNSYLVANIA, ASSIGNOR T0 STANDARD STEEL CAR COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION F PENNSYL- To all whom t may concern vaina.

Application ledl November 14, 1914, Serial No. 872,156.

Be it known that I, 'XNDREW CHRISTIAN- soN, a citizen of the United States, and resident of Butler', in the county of Butler and State of Pennsylvania, have invented a new and useful mprovement in Steel Box-Cars; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to box cars in which the side, roof and under-frame are constructed of suitable steel beams or sections while the covering for the sides'and roof is composed of plates of sheet steel secured to the framework and to each other in a manner to provide an exceedingly strong construction, and one which may be assembled with the greatest economy of material and labor. A further object of the invention is to strengthen. andat the same time, to simplify the construction of the several parts of the car, and also to provide a car, particularly, though not exclusively, adapted for carrying grain and like substances in bulk, and a construction from which a cargo of this character may be discharged, leaving the car entirely clean and clear.

With these objects in view, the invention consists in the construction and arrangement of parts, hereinafter to be described, though it is to be understood that the present embodiment of the invention here shown is presented for illustrative purposes, invention broadly is not confined to such embodiment.

In the drawings, which illustrate a preferred form of the invention, Figure 1 is a side elevation of so much of the car body as is necessary to illustrate the invention; Fig. 2 is a plan view with half of the roof covering removed; Fig. 3 is a horizontal sectional view through the car body above the oor, and with the Hoor in part removed to more clearly show-.the under-frame construction in plan; Fig. 4 ispan end elevation of the car body; Fig. 5 is a transverse section, the right-hand half being taken transversely through the car between the transoms, while the left-hand portion is taken transversely through the car door, the transoms being omitted to showthe bolster', Fig. `6 is a lon- .gitudinal vertical section on the line 6-6, Fig. 2; Fig. 7 is an enlarged transverse sectional view taken through the side-plate and speciacation of Letters Patent.

roof; and Fig. 8 is an enlarged detail of the end construction at the floor.

In the embodiment of the invention herein selected for illustration and referring to Fig. 1, the side walls of the car are composed of the plates 1-1-1, extending vertically from Hoor to roof, and these side plates as more clearly illustrated in Fig. 3, are overlapped as at 2 and riveted together as at 3 by rivets which pass through the edgesof said plates and through one flange 4 of the side-stakes 5, which lextend vertically inside the car. The alternate plates adjacent the overlapping edges are riveted as at 6 tothe opposite flange of the sidestakes 5; thus by a single line of rivets 3, these plates are fastened together and to the side-stakes. y

Referring to Fig. 5, it will be seen that the lower ends of these side-wall members are riveted at 7 to the side-sills 8, while the upper ends of the side-wall plates-are riveted between the downwardly extending portion 9 of the side plates proper, and at each sidestake, the downwardly extending portion 10 of a socket member 11 within which the outer end of the carline 12 hereinafter described is seated. Between these socket members, of course, the upper end of the side-wall plate 1 is riveted only to the side plate 9.

The end Walls of the car are similarly constructed and comprise the end-wall plates 1 of the same construction as the side wall plates and secured to outside end-stakes 13l and to end plate 14 in the same manner. As shown in Fig. 3, the outer edges of the end plate 1 are flanged as at 15 and riveted to the edges of the side-wall plates, thus forming a tight joint at the corners of the car. The lower ends of the end-wall plates as shown in Fig. 4, are riveted to the upstanding flange 16 of a transverse angle strip whose horizontalllange 17, Fig. 3, is riveted to the tops of the longitudinal sills of the under-frame; the lower edge of the end plate being flanged as at 15"-, As illustrated in the enlarged view, Fig. 7, the side plates'9 have the outwardly extending portions 19 and a depending lip 20, which not only greatly strengthens the joint between the roof and the side-walls and forms a strong eave for the car roof, but carries the drip from `the roof well away from the door opening of. the car. The end plate 14 as shown in Fig.=6, is of similar construction and provides a strong construction for the end of the car roof. e

The roof structure consists of the transverse channel sections 21, Fig. 6, while the roof coverin' consists of plates 22 overlapping'at t eir edges as at 23, said overlapped edges being secured by a single line 'of rive-ts together and to one flange 24 of the carline 21. The opposite flange of said carline is riveted to the adjacent roof plate and by the same line of rivets, supports 25 for the runway 26 are secured to the roof. From theinspection of Fig. 6, it will be seen that thel carlines 2l are staggered in relation to the side-stakes 5, and the outer ends-of said carline are secured and seated within the socket members 11, Figs. 6 and 7. The side-sills 8, Fig. 5 are of channel form and have a shallow lower flange 27 and a wide upper lange 28. Between these flanges are seated the outer ends of the transoms 29 which are riveted to the side-- sills as at 30. The outer ends of the bolsters 32 also are seated between these flanges ofthe side-sills, and secured to the side-sills in the same manner. The center-sill of the carv may consist of a box-girder 33 to which the linner ends ofthe bolster members 32 `and of the transoms' are, secured. The upper faces of the bolster androf the transoms respectively, are depressed as a-t 34 and 35, Fig. 5, to receive the longitudinal floor-sills or supports 37 to which the floor boards 38 are secured. The outer ends of lloorboards -rest upon the extended or widened portions corners is lled with triangular lstrips 40 ofl a length equal to the distance between adjacent side-stakes. The lower ilange of the transverse angle strip 16, Fig. 8, at the end of the car, extends beneath the end lloor board, thus efl'ectually closing any gap between the iloor and the end-wall of the car, and 1f desired, a transverse strip similar to the strips 40,'Fig. 5, may be extended across the end of the car to facilitate'the cleaning of the corners at this point in the manner described.

rIhe door construction comprises the following general features of construction. The frame of the door is formed of a Z- bar or section 41, to the inwardly extending Hange of which the adjacent edgesof shallwheels 49 ofthe bracketsv 50 by which the de or is suspended. This depending lip 47 of the track or` runway, therefore, not only forms a weather strip for the .upper edge 'of the door butl also serves to keep the wheels ofthe suspending bracket on the runway. The .saine flange 46 of the frame 'member of the door at the bottom, may

travel in the guide-brackets 51, Fig. 5, whereby the door is held against outward swinging.

While I have herein described a particular embodiment of my invention, it is to be understood that the same may be altered in details of construction and relative arrangement of parts within the scope of, the appended claims.

What I claim is: 1. In a car.`structure, the combination with channel-shaped, inwardly opening side sills, and channel-shaped, downwardly opening side-plates, and channel-shaped, laterally flanged side-stakes secured to said sills and said side-plates respectively, of side wall plates having overlapping edges secured to one flange of an adjacent side-stake by a single line of rivets, the lower end ofeach side wall late being secured to the web of said side-S111 and the inside depending flange of said side-plate. 2. In a car structure, the combination of a channel-shaped inwardly opening side sill, and a channel-shaped, downwardly opening side-plate, the latter having its inner flange of greater depth than its outer flange whereby said inner ilange forms means for securing of side wall plates thereto, and the outer flange forms a drip member for the roof,

and channel-shaped side-stakes having their v ends secured to said side-silland said sideplate respectively.

3. In a car structure, the combinationv with a channel-shapedside-sill and a channel-shaped side-plate, and channel-shaped side-stakes having j laterally extending flanges, the 'ends of said side-stakes being secured respectively to said side-sill and said side-plate, channel-shaped carlinesl having their end's secured to saidl sidelates at the opposite sides of the car, the side walls of' the car consisting of plates having overlapping edges secured to one Hange of the adjacent side-Stakes by a single lineof rivets, the roof covering .consisting of roof plates extending transversely from side to side of the car and having overlapping edges weave@ secured to one flange ofthe adi-acentcarline by a single line of rivets.
